Mortality and causes of death in schizophrenic patients in Denmark.

A cohort consisting of 6178 people that were psychiatric inpatients with a clinical schizophrenia diagnosis in 1957 were followed up from 1957 through 1986, and their cause-specific mortality was determined. Mortality from cardiovascular diseases, lung diseases, gastrointestinal and urogenital disorders, accidents and suicide was increased, whereas mortality from cerebrovascular disorders was reduced. In the male patients cancer mortality was reduced whereas cancer mortality in the female patients was increased. Mortality from a number of causes that theoretically could be associated with side effects from neuroleptics was increased. Mortality from some causes of death used as a measurement of the quality of medical care was found to be slightly increased. Further studies of the quality of the medical care provided to schizophrenic patients and of the association between neuroleptic medication and mortality are needed.
